The ultrasonic aspirator (CUSA, Cavitron Ultrasonic Surgical Aspirator) is an important surgical instrument in neurosurgery. Ultrasonic aspiration originated in dentistry and was later used in liver surgery. The technology of the ultrasonic aspirator is based on the combination of ultrasonic fragmentation with aspiration and irrigation. In this form, ultrasound destroys soft tissue while being gentler on blood vessels.
